As originally reported, the mobile version of Firefox (Fennec) is improving fast; the first builds for Windows Mobile are even able to complete a large part of the Acid3 test:

The first “official” alpha release of Fennec will become available this week for people using a Nokia N810; versions for Windows Mobile will follow later this year. These will all be alpha releases; a beta version is expected in 2009.

Just in case you hate this new feature as much as I do: you can find tips for making it behave more like 2.0 here.
